Product Overview: KEB 10.BR.100-6270 Rectifier
The KEB 10.BR.100-6270 is a high-precision electronic rectifier designed to power and control electromagnetic brakes and clutches, specifically from the KEB COMBISTOP and COMBINORM series. This bridge rectifier converts alternating current (AC) from the mains into the direct current (DC) required for the excitation of electromagnetic coils. It is a critical component in motion control systems where reliable braking and holding functions are mandatory for machine safety.
Technical Specifications and Switching Performance
The 10.BR.100-6270 is engineered for high switching frequencies and inductive load handling. It provides a stable DC output, ensuring that electromagnetic brakes engage and disengage with minimal latency. Its compact, encapsulated design protects the internal electronics against dust and vibration, making it suitable for direct mounting in terminal boxes or industrial control cabinets. The bridge configuration ensures efficient power conversion with low ripple voltage.

Operational Benefits and Safety
Using the genuine KEB 10.BR.100-6270 rectifier ensures that the air gap and engagement times of your electromagnetic brakes remain within factory tolerances. This prevents unnecessary wear on friction linings and reduces heat buildup within the coil. The integrated protection circuits safeguard the unit against inductive voltage peaks that occur during the rapid de-energization of the brake, significantly extending the service life of the entire drive system.
